To confirm a transaction in payment card systems, secret keys are used, which are stored either on magnetic stripes or chips. In order to steal them, a special hardware is needed and such attacks are hard to implement on a large scale. However, on mobile wallets and payment applications, secret keys are vulnerable to numerous threats.

One threat is a customer's device becoming infected with malware. Secret keys can be stolen easily from an unprotected application, potentially affecting millions of devices. Secret keys and user's credentials can be compromised, resulting in billions of fraud payments. For cryptocurrency wallets, having a private key means that all the funds in the wallet are available to a potential attacker.

Licel created the DexProtector Crypto Module to protect secret keys from being stolen. It combines the standards of the world's major payments systems on securing payments and wallets with the cutting-edge techniques and technologies, including:
